LEWIS JACOB RUTH, OF LEAMINGTON, CANADA.

ACETYLENE-GAS APPARATUS.

SPECIFICATION forming part of Letters Patent No. 640,705, dated January2, 1900.

Application filed August 10. 1898.

To all whom it may concern:

Be it known that I, LEWIS JAooB RUTH, of Leamington, in the Province ofOntario and Dominion of Canada, have invented a new and ImprovedAcetylene-Gas Apparatus, of which the following is a full, clear, andexact description.

My invention relates to improvements in the construction ofacetylene-gas generators.

My invention comprises the novel features hereinafter described andclaimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a sectional elevation taken through the generator upon theline 1 1 of Fig. 2. Fig. 2 is a top plan View of the apparatus. Fig. 3is a sectional elevation taken upon the line 3 3 of Fig. 1.' Fig. tis asectional elevation taken through the valve for controlling thewater-supply, and Fig. 5 is an outside elevation showing the mechanismfor turning the carbid-containing cylinder.

My invention relates to that class of acetylene-gas apparatus in whichthe generator and gasometer are separated and the carbid is placedwithin a perforated or grated cylinder, which may be revolved, and thewater is supplied thereto by means of a perforated pipe or spray locatedabove the cylinder. The gasometer is of the usual form,consisting of atank A, open at the top, and a bell A of smaller size within the tank Aand rising and falling with the generation and use of the gas. The gasis introduced to the gasometer by means of a pipe A which connects withanother pipe A leading from the gasometer to the generator. Thegenerator is contained within the receptacle D, which is, as hereinshown, of a square outline, having a tapered and sloping bottomterminating in an orifice normally closed by the clamping device D Thegenerator is open at the top and is closed by a Water-seal device. Atits upper end the generator-chamber is provided with a second wall D,forming between itself and the outer wall of the generator a spaceadapted to receive water and to form a water seal.

The cap F is provided with a downwardlyextending flange F, adapted toenter this annular space and reaching nearly to the bottom Serial No688,294. (No model.)

thereof. When the cap F is placed in position and the space between theouter wall of the generator and the part D thereof is filled with water,the generator will be tightly closed.

Upon the upper surface of the cap F is pivoted a bar G, which is furtherheld in place by means of guides f. The ends of the bar G extend beyondthe sides of the top F. Proj ectin g upward from the generator are lugsd, formed as books and adapted to be engaged by ,the projecting ends ofthe bar G. These hooks project in opposite directions, so that" when thecap is placed in position and the bar G is given a slight rotation uponits pivot the ends of the bar will be forced beneath the hooks d and thetop is prevented from rising.

It is evident that the generator may be made of circular outline,as wellas rectangular. The construction would differ in no essential featuresif this were done.

The pipe A connecting the generator with the gasometer, extends upwardWithin the generator to near the top thereof. Mounted within thegenerator is a cylinder E, as herein shown, formed of two headsconnected by a series of rods placed closely together. rods are placedclose enough together to prevent the carbid from dropping through. Thecylinder is provided with a door E, which is hinged at e and providedupon its opposite side with a button 6 or other device for securing thesame. The shaft E of this cylinder extends outside the generator,passing through a stuffing-box on the way.

Upon that portion of the shaft outside of the generator is mounted apinion J. This pinion is loose upon theshaft, but is provided with aspring-held pawl J adapted to engage the teeth of a ratchet-wheel Jwhich is secured to the shaft. By this means rotation of the pinion inone direction will rotate the shaft, while rotation in the otherdirection will have no effect upon the shaft. The pinion is turned byengagement with the rack I, which is connected at its upper end with thegasometer-bell A and rises and falls therewith. Connected with the samesupport is a guide-bar I, which is parallel with the rack I. Both ofthese bars pass through guides 1 secured upon the outer tank A of thegasometer.

The water for generation of the gas is con- These tained in a tank B,which is mounted above the generator. From this tank leads a pipe 13.This pipe enters the generator and has an upwardly-extending armterminating in a horizontal section B of perforated pipe, located abovethe cylinder E. When the water flows through the pipe B, it is thusdeposited upon the carbid within the cylinder in the form of a spray orin fine jets. Between the generator and the tank B a valve 7) isinserted in the pipe B. This valve is shown in detail in Fig. 4:. Itcomprises a chamber 12', located above the valve proper and terminatingat its lower end in a partition or diaphragm containing a valve-seat bon its under side. This diaphragm is also provided with a centralopening, through which the water flows. Connected to the lower end ofthe cylinder b isv a second cylinder 11 having a valve-seat b in itslower portion. Between these two valve-seats is the valve 12 which isadapted to be seated upon either valve-seat. The continuation of thepipe B is attached to the cylinder b The stem of the valve extendsoutward through the upper end of the cylinder 7) and is connected to alever G. This lever is supported at one end upon a standard C and at theopposite end is connected to a chain 0 which extends downward to aconnection with the gasomei'er-bell A, so that when the gasometer-bellhas fallen to a certain point the valve 5 will be lowered from the seat32 and water admitted to the pipe B and conducted to the generator.

Surrounding the outer portion of the valvestem is a spiral spring 0',which normally holds the valve raised against the seat b and the lever Graised. It therefore acts in opposition to the gasometer-bell when thelatter is pulling down upon the chain 0 Should the gasometer-bellcontinue in its downward course, it will finally seat the valve upon thelower seat 5 Then in use, the lime formed by the decomposition of thecalcium carbid will be sifted out of the carbid by the turning movementgiven to the cylinder E when the gasometer-bell rises. This lime willfall upon the inclined bottom of the generator and may be removed whendesired by removing the clamp D When the gasoineter falls, the valve 5will be opened to admit water to the perforated pipe B This willdischarge the water upon the carbid within the cylinder E. Gas generatedthereby will cause the gasometor-bell to rise, and the admission ofwater will thus be cut off. The water seal at the upper end of thegenerator permits ready access to the generator and at the same timesecures a perfect seal, so that there can be no leaking of gas.

Connected to. the pipe A which conducts the gas from the generator tothe gasometer, is a drip-pipe a. A similar pipe h is connected to thepipe H, which conveys the gas away from the gasometer. These pipes areof U shape, connected at one end with the gas pipes and having theirother end open to the atmosphere. These drip-pipes are filled withwater, forming a trap to prevent escape of the gas and at the same timecollecting any water which may be contained in the pipes. The generatoris supported at the proper elevation upon legs D Having thus fullydescribed my invention,

I claim as new and desire to secure by Letters Patent- 1. In anacetylene-gas apparatus, the combination with a gasorneter, and agenerator containing a carbid-holder, of a water-tank abovethegenerator, 2. valve-chamber connected with the tank and havingoppositelyarranged valve-seats, a valve in the said chamber between theseats and having its stem projecting through thetop of the chamher, alever to which the valve-stem is pivoted, a spring surrounding thevalve-stem between the lever and the valve-chamber, a flexibleconnection between the lever and the gasometer-bell, and a pipe leadingfrom the valve-chamber into the generator above the carbid-holder,substantially as described.

2. An acetylene-gas apparatus, comprising a gasometer, agenerator-casing, an openwork carbid-cylinder mounted in thegenerator-casing, means for revolving the carbidcylinder from thegasometer-bell, a watertank, a valve-chamber connected with thetank andhaving oppositely-arranged valveseats, a valve in the chamber betweenthe seats and having its stem projecting through the top of the chamber,a pivoted lever to which the valve-stem is secured, a spring surroundingthe valve-stem between the lever and valve-chamber, a flexibleconnection between the lever and the gasometer-bell, and a pipe leadingfrom the valve-chamber into the generator-casing above thecarbid-cylinder, substantially as described.
